Abstract:
Objective To investigate the effect of ropivacaine combined with dexanmethasone sprayed intratracheally in patients with resistant tubes and postoperative sore throat.Methods Eighty patients ASA Ⅰ-Ⅱ grade undergoing laparoscopic cholecystectomy were randomly divided into four groups by random digits tabel method,20 patients in each.2 ml of 0.75％ ropivacaine combined with 1 ml dexamethasone (group A) ; 2 ml of 0.75％ ropivacaine combined with 1 ml 0.9％ sodium (group B) ; 3 ml of 1％ tetracaine (group C); 3 ml of 0.9％ sodium (group D) were immediately intratracheal sprayed before intubation.The resistant tubes and degree of postoperative 24 h sore throat [by visual analog scale (VAS) scores],comfort [by Bruggrmann comfort scale (BCS) scores] and the incidence of sore throat were recorded.Results The resistant tubes appraised rate in group A,B and C was higher than that in group D [65.0％ (13/20),60.0％ (12/20),70.0％ (14/20) vs.5.0％ (1/20)] (P ＜ 0.05),but there was no significant difference among group A,B and C (P＞ 0.05).The incidence of sore throat at 24 h after surgery in group A,B and C was lower than that in group D [20.0％(4/20),25.0％ (5/20),25.0％ (5/20) vs.90.0％ (18/20)] (P ＜ 0.05),but there was no significant difference among group A,B and C (P＞ 0.05).The VAS and BCS scores in group A were better than those in group B,C and D [(0.52 ± 1.14) scores vs.(1.68 ± 1.42),(1.59 ± 1.33),(4.22 ± 1.95) scores,(2.80 ± 1.54) scores vs.(1.60 ± 1.19),(1.80 ± 1.20) and (0.45 ± 0.81) scores] (P ＜ 0.05),but there were no significant differences between group B and group C (P ＞ 0.05).Conclusion Ropivacaine combined with dexamethasone sprayedintratracheally can significantly increase the degree of postoperative resistant tubes,decrease the rate of sore throat after general anesthesia,and increase patient' s comfort.
